Abstract
Calciphylaxis (CP) is a serious, potentially life-threatening disease that presents with medial calcification of small-sized vessels and painful ischemic ulcerations. Although calciphylaxis is frequently seen in patients with end-stage kidney disease on dialysis (calcific uremic arteriolopathy, CUA), there are reported cases of nonuremic calciphylaxis (NUC), which often remain undiagnosed. We conducted a retrospective chart review at our dermatological hospital and evaluated data concerning the epidemiology, comorbidities, medication, laboratory abnormalities, and therapeutic approaches of 60 patients diagnosed with calciphylaxis between 01/2012 and 12/2022. We identified 21 patients diagnosed with NUC and 39 with kidney disease. The predilection sites of skin lesions were the lower legs in 88% (n = 53), followed by the thigh and gluteal regions in 7% (n = 4). Significant differences were identified in comorbidities, such as atrial fibrillation (p < 0.001) and hyperparathyroidism (p < 0.01) accounting for CUA patients. Medication with vitamin K antagonists (p < 0.001), phosphate binders (p < 0.001), and loop diuretics (p < 0.01) was found to be associated with the onset of calciphylaxis. Hyperphosphatemia (p < 0.001), increased parathyroid hormone (p < 0.01) and triglyceride levels (p < 0.01), hypoalbuminemia (p < 0.01) and decreased hemoglobin values (p < 0.001) in the CUA cohort were significantly different from those in the NUC group. All patients with CUA received systemic medication. In contrast, only 38% (n = 8) of patients with NUC received systemic treatment. Striking discrepancies in the treatment of both cohorts were detected. In particular, NUC remains a disease pattern that is still poorly understood and differs from CUA in several important parameters.

Abstract
Penile calciphylaxis is a rare and severe complication primarily observed in patients with end-stage renal disease (ESRD) undergoing dialysis. A 50-year-old man presented with severe penile pain and phimosis. He had a history of hypertension and diabetes mellitus for 10 years, complicated by ESRD and was awaiting a cadaveric kidney transplant. He was on cinacalcet therapy for tertiary hyperparathyroidism. The patient underwent circumcision at which discolouration and necrotic patches involving the glans penis were noted. The histological findings were consistent with calciphylaxis and suppurative inflammation. However, due to persistent severe pain and progressive gangrene, a partial penectomy was performed. This report demonstrates the importance of consideration of calciphylaxis in patients with ESRD when presenting with penile pain, even phimosis.

Abstract
Calciphylaxis is a unique medical condition characterized by calcification of the medial layer of arterioles and soft tissues in a patient's skin at the level of the dermis and subcutaneous adipose tissue. The rate of progression of calciphylaxis is rapid, starting with a reduction of blood flow that leads to ischemic changes in the skin that can manifest as painful cutaneous erythematous nodules or plaques and later as skin ulceration. The majority of patients affected by calciphylaxis have predisposing comorbidities such as end-stage renal disease with a long history of hemodialysis and electrolyte abnormalities in calcium, phosphate, and parathyroid hormone levels. This report presents the case of a 72-year-old female patient on hemodialysis who developed calciphylaxis. The methods for early prognosis (the methods of early diagnosis), including clinical presentation, risk factors, imaging techniques, and laboratory investigations, are discussed. The presented case is particularly noteworthy given the onset of calciphylaxis within a mere three months of initiating hemodialysis, a timeline significantly shorter than the typically observed period in most patients. (The case detailed in this report outlines the rapid onset of calciphylaxis in a patient who was receiving hemodialysis for only three months.) This patient with early-onset calciphylaxis highlights the unpredictable nature of calciphylaxis and the need for increased clinical vigilance even in the initial stages of hemodialysis.

Abstract
Nonosseous abnormalities are often seen on bone scans and can be related to a wide variety of pathology ranging across vascular, infection, and inflammatory etiology. Diffuse soft tissue radiotracer uptake on bone scans is typically attributed to renal or metabolic derangements. Calciphylaxis is the deposition of calcium in small blood vessels, skin, and other organs leading to vascular obstruction and skin necrosis. It is a rare disorder with unknown pathophysiology. Diagnosis of calciphylaxis is challenging and requires an interdisciplinary approach including clinical findings, laboratory results, medical imaging, and skin biopsy. An early diagnosis is important as the disease is associated with high morbidity and mortality. The purpose of this review article is to highlight the role of bone scintigraphy in the evaluation of calciphylaxis and to correlate the findings with other imaging modalities and histopathology.

Abstract
Calciphylaxis is a rare and severe medical condition characterized by the calcification of small blood vessels and soft tissues, leading to tissue damage, skin ulcers, and intense pain. It most commonly affects individuals with underlying health conditions such as kidney disease, particularly end-stage renal disease (ESRD), and is associated with high mortality rates. Understanding the diagnosis and management of calciphylaxis is crucial for improving patient outcomes. Diagnosing calciphylaxis can be challenging due to its rarity and overlapping symptoms with other skin conditions. Healthcare professionals typically use a combination of clinical evaluation and diagnostic tests to reach a conclusive diagnosis. The management of calciphylaxis is multifaceted and typically involves a collaborative effort between various healthcare specialists, including nephrologists, dermatologists, and wound care experts. The primary goals of treatment are to alleviate pain, promote wound healing, address underlying causes, and prevent further complications.

Abstract
Calciphylaxis is a debilitating condition associated with significant morbidity and mortality, often associated with patients with end-stage renal disease, in which the calcification of cutaneous arterioles and small arteries occurs, leading to subsequent ischemia and cutaneous infarction. Herein, we report the case of a diabetic patient with end-stage kidney disease on dialysis, presenting multiple intensely painful necrotic plaques on the lower extremities. The suspicion of calciphylaxis was raised based on the patient's medical history and clinical presentation, subsequently confirmed by radiological examination, which revealed calcifications along vascular pathways. Diagnosis can be established based on clinical and paraclinical grounds alone, and some clinicians may forego skin biopsy and initiate treatment presumptively. The management of calciphylaxis remains a challenge and requires a multidisciplinary approach since most patients experience intense pain that is often unresponsive to conventional analgesics, leading to a reduced quality of life.

Abstract
Calciphylaxis is an uncommon but life-threatening syndrome in end-stage kidney disease, characterised by painful medial and intimal calcification of the arterioles in the deep dermis and subcutaneous tissues. Intravenous sodium thiosulfate serves as an off-label but effective treatment in haemodialysis patients. However, this approach confers considerable logistical challenges for affected peritoneal dialysis patients. In this case series, we demonstrate that intraperitoneal administration can be a safe, convenient and long-term alternative.

Abstract
Introduction and importance Calciphylaxis manifests clinically by skin ischemia and necrosis and histologically by calcification of dermal arterioles. Usually, it occurs in patients with end-stage renal disease on dialysis or in patients who had a kidney transplant. Here, the authors present a case of calciphylaxis occurring in a patient with psoriasis and psoriatic arthritis. Case presentation A 66-year-old Syrian male with a history of psoriatic arthritis presented for evaluation of 2-month nonpainful ulcers on his feet and hands that were treated with warfarin. Biopsies confirmed the diagnosis of calciphylaxis. The patient received sodium thiosulfate, zoledronic acid, intralesional sodium thiosulfate injections, and an intravenous infusion of vitamin K with dramatic improvement. At the 3-month follow-up, his wounds had been completely remitted. Discussion Nonuremic calciphylaxis occurs in many cases, like vitamin D administration, vitamin K antagonists' administration, chronic inflammation, and others. The association between calciphylaxis and psoriasis was reported only in four cases in the literature; meanwhile, this was the first case that described calciphylaxis in the setting of psoriatic arthritis. Conclusion A suspicion of calciphylaxis should be maintained in patients with underlying inflammatory mechanism diseases.

Abstract
A multimodality approach has been proposed as an effective treatment for calciphylaxis in patients with end-stage kidney disease. In this retrospective study, we report the cases of 12 end-stage kidney disease patients from l'Hôtel-Dieu de Québec hospital (Canada) who were diagnosed with calciphylaxis between 2004 and 2012 and treated with a multimodality clinical approach including sodium thiosulfate (STS). Statistical analyses were performed to evaluate the impacts of patients characteristics, the different interventions as well as therapy regimen on the therapeutic response. The majority of patients (n = 9) were hemodialyzed. The patients-associated comorbidities were consistent with previously reported risk factors for calciphylaxis: Diabetes (n = 11), calcium-based phosphate binders use (n = 10), warfarin use (n = 9), obesity (n = 7), female gender (n = 8) and intravenous iron use (n = 8). STS was given for a median duration of 81 days. 75% of the patients had a response (total or partial) including a complete response in 42% of patients. One-year mortality rate was low (25%). STS was used during a mean duration of 83.33 ± 41.52 days and with a total cumulating dose of 1129.00 ± 490.58 g. The recorded mean time before a complete response was 102.20 days (51-143). Pain improvement occurred after a mean time of 8.67 ± 10.06 days. None of the studied factors was statistically associated with a complete or a partial response to the multimodality approach. Although our data have a limited statistical power, they support treating calciphylaxis with a multimodality approach including STS as its effects are independent from important clinical variables.

Abstract
Calciphylaxis, or calcific uremic arteriolopathy, is a rare and deadly disease that affects patients with end-stage renal disease (ESRD). It typically manifests in the abdomen and lower extremities. We present a case of a 59-year-old female patient on dialysis due to ESRD who complained of a three-week history of hemorrhagic and painful bilateral lower limb lesions. The predominant clinical suspicion was warfarin-induced skin necrosis (WISN); however, the persistence of unresolved skin lesions post-warfarin cessation generated the impression of calciphylaxis. A skin biopsy confirmed the classical histological findings associated with calciphylaxis. This paper highlights the possible importance of warfarin being an inciting event, as well as the early differentiation between the presentations of WISN and calciphylaxis.

Abstract
Limited data are available on the utilization of sodium thiosulfate (STS) treatment for calciphylaxis in peritoneal dialysis (PD) patients, while it is well-studied in hemodialysis (HD) patients. A systematic literature search was conducted using Ovid MEDLINE, EBM Reviews-Cochrane Central Register of Controlled Trials, and EBM Reviews-Cochrane Database of Systematic Reviews to identify reported cases of PD patients with calciphylaxis who received STS. The search covered the inception of the databases through August 2022. Across 19 articles, this review identified 30 PD patients with calciphylaxis who received STS. These included 15 case reports, 2 case series, and 2 cohort studies. The administration routes and doses varied depending on the study. For intravenous (IV) administration (n = 18), STS doses ranged from 3.2 g twice daily to 25 g three times weekly for 5 weeks to 8 months. Outcomes included 44% of patients experiencing successful wound healing, 6% discontinuing STS due to adverse effects, 67% transitioning to HD, and 50% dying from calciphylaxis complications. For intraperitoneal (IP) administration (n = 5), STS doses ranged from 12.5 to 25 g three to four times weekly for 12 h to 3 months. Results showed 80% of patients achieving successful wound healing, 80% discontinuing STS due to adverse effects, 40% transitioning to HD, and 20% dying from IP STS-related chemical peritonitis. In cases where patients switched from IV to IP STS (n = 3), doses ranged from 12.5 to 25 g two to three times weekly for 2.5 to 5 months. Among them, 67% experienced successful wound healing, while 33% died from sepsis. Two cases utilized oral STS at a dose of 1500 mg twice daily for 6 and 11 months, resulting in successful wound healing without adverse effects or need for HD. However, one patient (50%) died due to small bowel obstruction. This systematic review provides an overview of STS treatment for PD patients with calciphylaxis. Although successful treatment cases exist, adverse effects were significant. Further research, including larger clinical studies and pharmacokinetic data, is necessary to establish the optimal route, dose, and efficacy of STS in PD patients.

Abstract
In this report, we present a 57-year-old man with chronic bilateral lower extremity wounds from nonuremic calciphylaxis, which were successfully reconstructed using a piscine-derived acellular dermal matrix. The acellular dermal matrix incorporated quickly, providing a wound bed that was amenable to skin grafting. We demonstrate that this is an effective off-the-shelf solution for these chronic wounds, resulting in pain reduction and complete closure of the wounds, allowing the patient to return to his previous baseline activities, and improving his quality of life.

Abstract
BACKGROUND Normal-renal calciphylaxis (NRC) is a devastating calcific vasculopathy characterised by refractory wounds. It is more likely to be misdiagnosed because of the absence of renal insufficiency. Failure to effectively control may lead to rapid deterioration and ultimately death. However, current knowledge of it is still inadequate. OBJECTIVES To provide a relatively comprehensive review of NRC. METHODS Nine electronic medical databases including PubMed, Web of Science, Embase, the Cochrane Library and so on were searched from inception to April 1, 2022. Articles in which calciphylaxis was diagnosed in patients with normal renal function were included. RESULTS Totally 140 articles were retrieved with 187 patients (median age, 62 years [IQR, 49.63 ~ 75.70 years]; 83.42% female; 84.5% Caucasian). Vitamin K antagonism (43.32%) and diabetes (39.57%) accounted for most of the concomitant factors. Cutaneous presentations were the most common. Pathological confirmation was made in 97.86% of patients with an accuracy of 99.45%. Multidisciplinary therapeutic strategies were usually implemented while the final prognosis was not ideal, with a 6-month mortality rate of 21.10% and a 1-year mortality rate of 27.52%. CONCLUSION NRC is an under-recognised disease caused by a variety of factors; meanwhile, multidisciplinary efforts are required to inform diagnostic and therapeutic decisions.

Abstract
AIM Calciphylaxis is a rare disease, predominantly in chronic kidney disease (CKD), characterized by high morbidity and mortality. Data from the Chinese population have been an invaluable resource for a better understanding of natural history, optimal treatments and outcomes of calciphylaxis. METHODS A retrospective study was conducted in 51 Chinese patients diagnosed with calciphylaxis at Zhong Da Hospital affiliated to Southeast University from December 2015 to September 2020. RESULTS Between 2015 and 2020, 51 cases of calciphylaxis were registered in The China Calciphylaxis Registry (http://www.calciphylaxis.com.cn), which was developed by Zhong Da Hospital. The mean age of the cohort was 52.02 ± 14.09 years, and 37.3% were female. Forty-three patients (84.3%) were on haemodialysis, with a median dialysis vintage of 88 months. Eighteen patients (35.3%) had a resolution of calciphylaxis and 20 patients (39.2%) died. Patients in later stages had higher overall mortality than those in earlier stages. Delay from skin lesions onset to diagnosis and calciphylaxis-related infections were risk factors in both early and overall mortality. Additionally, dialysis vintage and infections were significant risk factors in calciphylaxis-specific mortality. Among therapeutic strategies, only the use of sodium thiosulfate (STS) ≥3 courses (14 injections) was significantly associated with decreased hazard of death in both early and overall mortality. CONCLUSION For Chinese patients with calciphylaxis, delay from skin lesions onset to diagnosis and infections secondary to wounds are risk factors for the prognosis of patients with calciphylaxis. Additionally, patients in earlier stages have better survival and early continuous use of STS is highly suggested.

Abstract
Calciphylaxis is a life-threatening complication most often associated with chronic kidney disease that occurs as a result of the deposition of calcium in dermal and adipose microvasculature. However, this condition may also be seen in patients with acute kidney injury. The high morbidity and mortality rates associated with calciphylaxis highlight the importance to correctly diagnose and treat this condition. However, calciphylaxis remains a diagnosis that may be clinically challenging to make. Here, we review the literature on uremic calciphylaxis with a focus on its pathophysiology, clinical presentation, advances in diagnostic tools, and treatment strategies. We also discuss the unique histopathological features of calciphylaxis and contrast it with those of other forms of general vessel calcification. This review emphasizes the need for multidisciplinary collaboration including nephrology, dermatology, and palliative care to ultimately provide the best possible care to patients with calciphylaxis.

Abstract
BACKGROUND Sodium thiosulfate (STS) can be used to treat patients diagnosed with calciphylaxis, which is a rare life-threatening syndrome. However, our patients treated with the recommended STS regimen presented with serious adverse events, resulting in treatment withdrawal. Then an optimized STS regimen was used to increase the tolerance of patients to STS and improve treatment continuation. The curative effect of the new regimen is not yet definite. Therefore, this study aimed to evaluate the response to the use of the optimized STS regimen for the treatment of calciphylaxis in Chinese patients during the first three courses of treatment. METHODS Demographic, clinical, and laboratory data were retrospectively collected on 31 calciphylaxis patients with chronic kidney disease (CKD) or end-stage kidney disease (ESKD) treated with the optimized STS regimen. The primary outcome was a clinical improvement. The secondary outcomes included survival rate and adverse events. RESULTS Twenty-five patients (over 80%) achieved clinical improvement considering improvement or nonspecific changes of skin lesions (80.65%) and pain relief (100%). Furthermore, 54.84% of patients did not experience any adverse events and none died from complications. During a median follow-up of 9 months (interquartile range 4‒19), 27 patients (87.10%) survived; additionally, 13 patients (41.94%) survived after a one-year follow-up period. CONCLUSION The optimized STS regimen is relatively safe, associated with satisfactory outcomes, and well tolerated by patients for short to medium treatment duration. Hence, it is a promising approach for the treatment of patients diagnosed with calciphylaxis.

Abstract
Calcific uraemic arteriolopathy (CUA), also known as calciphylaxis, is a rare and often fatal condition, frequently diagnosed in end-stage renal disease (ESRD) patients. Although exact pathogenesis remains unclear, iron supplementation is suggested as a potential risk factor. Iron and erythropoietin are the main stay of treatment for anaemia in ESRD patients. Few observational studies support the role of iron in the pathogenesis of calciphylaxis although data from the pivotal trial was not strongly supportive of this argument, i.e., no difference in incidence of calciphylaxis between the low-dose and high-dose iron treatment arms. Elevated levels of vascular cell adhesion molecules in association with iron excess were postulated to the pathogenesis of CUA by causing inflammation and calcification within the microvasculature. In-addition, oxidative stress generated because of iron deposition in cases of systemic inflammation, such as those seen in ESRD, may play a role in vascular calcification. Despite these arguments, a direct correlation between cumulative iron exposure with CUA incidence is not clearly demonstrated in the literature. Consequently, we do not have evidence to recommend iron reduction or cessation in ESRD patients that develop CUA.

Abstract
Nonuremic calciphylaxis is a rare condition presenting with peripheral ischemic ulcerations. Calciphylaxis is the deposition of calcium and phosphate into arteriolar walls caused by exceeding their solubility range in the blood. It is most commonly seen in patients with end-stage renal disease; however, nonuremic calciphylaxis occurs in patients with normal or mildly impaired renal function. Risk factors for nonuremic calciphylaxis include Coumadin therapy, obesity, and diabetes mellitus. Histopathologic examination of deep skin biopsy containing subcutaneous adipose tissue reveals medial calcification of dermal and subcutaneous arterioles. This diagnosis must be managed locally with wound care and systemically by control of blood calcium solubility. Avoidance of infection is critical to survival. Here we report a case of calciphylaxis in a patient with normal renal function and serum levels of calcium and phosphorus who presented with gangrene of the extremities. Increased awareness of this debilitating disease will lead to earlier diagnosis, proper treatment and improved patient outcomes.

Abstract
Uremic calciphylaxis is a rare disease that affects patients with chronic end-stage renal disease. It is a pathology of the microvessels of the dermis and hypodermis which are calcified and whose thrombosis leads to skin necrosis. Calciphylaxis lesions can be distal and axial. They lead to pain, infection and are associated with denutrition and in high mortality rate (40-80% at 1 year). This general review describes the clinical and para-clinical presentations of calciphylaxis. It summarizes the current knowledge on its pathogenesis and the therapeutical options that can be proposed to improve the management and attempt to reduce the mortality of patients with uremic calciphylaxis.

Abstract
INTRODUCTION Non-dermatology medical specialties may refer patients for skin biopsies, searching for a particular diagnosis. However, the diagnostic impact of the skin biopsy is not clearly established. This article aims to assess the indications for, and evaluate the clinical relevance of, skin biopsies in non-dermatology medical specialties. METHODS A questionnaire was sent to 23 non-dermatology specialty departments in a university medical center, requesting a list of indications for skin biopsies, as well as to 10 staff dermatologists to collect the indications of skin biopsies requested by non-dermatology specialties. Once the indications were collected, a literature search was performed to evaluate their clinical value and relevance. RESULTS Eleven non-dermatology specialties provided a list of skin biopsy indications, to which staff dermatologists added seven more indications. A literature search revealed evidence-based medicine data for six diseases, that is, amyloidosis, peripheral autonomic neuropathy, Sneddon's syndrome, intravascular lymphoma, sarcoidosis, and chronic graft-versus-host disease. Results were questionable concerning infectious endocarditis, acute graft-versus-host-disease, and the lupus band test. Skin biopsy were not evidenced as useful for the diagnosis of calciphylaxis, systemic scleroderma, Behçet's disease, or hypermobile Ehlers-Danlos syndrome. For the diagnosis of Alport's syndrome, pseudoxanthoma elasticum, and vascular Ehlers-Danlos syndrome, skin biopsy is currently outperformed by genetic analyses. For diagnoses such as Henoch-Schönlein purpura and Sjögren's syndrome, skin biopsy represents an additional item among other diagnostic criteria. CONCLUSION The usefulness of skin biopsy as requested by non-dermatology specialties is only evidenced for amyloidosis, peripheral autonomic neuropathy, Sneddon's syndrome, intravascular lymphoma, sarcoidosis, chronic graft-versus-host-disease, Henoch-Schönlein purpura, and Sjögren's syndrome.

Abstract
Calciphylaxis is an uncommon but devastating disorder characterized by vascular calcification and subsequent cutaneous tissue necrosis. This results in exquisitely painful and slow healing wounds that portend exceptionally high morbidity and mortality. The diagnosis of this condition can be complicated because there are no conclusive serologic, radiographic or visual signs that this disease is manifesting. The differential of tissue necrosis is broad, and identifying calciphylaxis requires an adroit understanding of the risk factors and physical signs that should raise suspicion of this condition. Reviews on this subject are uncommon and lack directed commentary from disease experts on the best diagnostic approach for patients suffering from this disease. The goal of this article is to update practicing dermatologists on the current standard of care for calciphylaxis.

Smilnak G, Jiang M, Jain B. Calciphylaxis of the penis and distal digits: a case report. J Med Case Rep 2022; 16:18. [PMID: 35039083 PMCID: PMC8764786 DOI: 10.1186/s13256-021-03231-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Accepted: 12/14/2021] [Indexed: 11/29/2022] Open
Abstract
Background Calciphylaxis is a rare, often fatal disease resulting from calcification of dermal arterioles and capillaries. Usually diagnosed in patients with end-stage renal disease, this disorder typically presents as necrotic, nonhealing ulcers in acral or adipose areas. Here we report the case of an elderly man who was found to have calciphylaxis of the distal digits and penis, the latter of which is an uncommon site of disease that carries a particularly poor prognosis. Case presentation A 73-year-old African American man with multiple medical comorbidities including dialysis-dependent end-stage renal disease presented with worsening painful, necrotic lesions on his glans penis and several distal digits over the last 2 months. The wound on the glans was foul smelling with overlying purulence and had been unsuccessfully treated with amoxicillin–clavulanic acid. Discovery of diffuse intravascular calcification on computed tomography, in addition to a markedly elevated calcium–phosphate product immediately prior to the onset of his ulcers, led to the diagnosis of calciphylaxis. The patient was initiated on sodium thiosulfate without improvement in his lesions, and he died 3 months later after another prolonged hospitalization. Conclusions While calciphylaxis is a rare disease, involvement of the distal digits and especially the penis is even more uncommon and portends a particularly poor prognosis: 6-month mortality rates are reportedly as high as 70%. This suggests that prompt recognition and management of the disease is required; however, despite receiving standard therapy, our patient failed to experience improvement in his disease and instead developed several more fingertip ulcers at blood glucose sample points during his hospitalization. A corollary of the case presented here is the need for more effective management of calciphylaxis, especially for patients in whom uncommon sites, such as the penis, are involved.

Abstract
OBJECTIVE Granuloma formation following self-administered cosmetic oil injections can lead to severe hypercalcemia and renal calcifications due to extra-renal vitamin D activation. This translational study aims to identify Prednisolone sparing therapeutics for hypercalcemia after development of granulomatous disease secondary to paraffin oil injections. MATERIALS AND METHODS Granuloma tissue isolated from five men were cultured ex vivo and treated with selected drugs to block generation of activated vitamin D (1,25(OH)2D3). In a retrospective study, we included data before and during different treatments of 21 men with paraffin oil induced granulomatous hypercalcemia (46 treatment courses) where serum calcium, parathyroid hormone, vitamin D metabolites, creatinine and inflammatory markers were measured. RESULTS Addition of Ketoconazole or Ciclosporin to granuloma tissue ex vivo culture, significantly suppressed production of 1,25(OH)2D3 after 48 h (both p < 0.05). Prednisolone was the first treatment option in most men and lowered serum levels of ionized calcium after 1, 2, 3 and 6 months compared with baseline (p < 0.05). Ketoconazole or Hydroxychloroquine had no significant effect on serum calcium levels and were unable to reduce the concomitant daily Prednisolone doses (p > 0.05). Azathioprine did not reduce calcium levels. However, addition of Tacrolimus to Prednisolone treatment enabled a reduction in Prednisolone dose after 3 months (p = 0.014), but with no additional effect on calcium homeostasis. CONCLUSION This study verifies that Prednisolone is an effective treatment and suggests that calcineurin inhibitors may be used as Prednisolone sparing treatment for paraffin oil-induced granulomatous hypercalcemia. Randomized clinical trials are needed to determine clinical efficacy.

Abstract
Calcific uremic arteriolopathy, commonly referred to as “calciphylaxis,” is a rare life-threatening condition observed in patients with chronic kidney disease and end-stage renal disease on dialysis. This results in necrotic, ischemic, tender dermal lesions anywhere in the body, but mainly on the abdominal wall and lower extremities, where subcutaneous tissue is abundant. Histologically, it is defined by calcification in dermal capillaries, arterioles, and subcutaneous adipose tissues. It can occur in all advanced stages of chronic kidney disease as well as end-stage renal disease patients on hemodialysis or peritoneal dialysis. Our case highlights a successful case of calciphylaxis in a young female patient who underwent parathyroidectomy and intensification of peritoneal dialysis regimen along with the infusion of sodium thiosulphate injection resulting in complete resolution of the lesion in 3 months. With limited evidence of treatment options and increased frequency of this condition in a dialysis patient, our case highlights the key aspects of calciphylaxis management in a young end-stage renal disease patient who didn’t need a change of dialysis modality. We also review the risk factors and current practiced management options of this condition in our article.

Abstract
BACKGROUND Calciphylaxis is an ischemic vasculopathy with high morbidity and mortality. Early and accurate diagnosis is critical to management of calciphylaxis. Clinical mimickers may contribute to delayed or misdiagnosis. OBJECTIVE To assess the rate and risk factors for misdiagnosis and to identify clinical mimickers of calciphylaxis. METHODS A retrospective medical record review was conducted of patients with calciphylaxis at a large urban tertiary care hospital between 2006 and 2018. RESULTS Of 119 patients diagnosed with calciphylaxis, 73.1% were initially misdiagnosed. Of patients not initially misdiagnosed, median time to diagnosis from initial presentation was 4.5 days (interquartile range, 1.0-23.3), compared to 33 days (interquartile range, 13.0-68.8) in patients who were initially misdiagnosed (P = .0002). The most common misdiagnoses were cellulitis (31.0%), unspecified skin infection (8.0%), and peripheral vascular disease (6.9%). Patients who were misdiagnosed frequently received at least 1 course of antibiotics. Patients with end-stage renal disease were less likely to be misdiagnosed than those without this disease (P = .001). LIMITATIONS Single-center, retrospective study. CONCLUSIONS Understanding the risk factors for misdiagnosis of calciphylaxis is an opportunity for further education concerning this rare disease.

Abstract
Calcific uremic arteriolopathy, termed calciphylaxis, was previously considered a condition that developed mostly in patients requiring dialysis. It has now been described in kidney transplant patients, in advanced chronic kidney disease (CKD) patients not requiring dialysis, and in individuals with maintained kidney function. We describe an individual with CKD stage 3b with hypercalcemia who presented with features highly specific for calciphylaxis based on results of a skin biopsy. The condition has high morbidity and mortality, and thus prompts immediate cessation of the offending agents or treatment of the cause. The following case and literature review demonstrates a need for a detailed assessment of patients’ risks and exposures and expanding the differential diagnosis to include calciphylaxis in nonuremic patients with necrotic ulcers with a plan for early imaging and possible biopsy.

Abstract
RATIONALE The recognition of calciphylaxis often eludes practitioners because of its multiple ambiguous presentations. It classically targets areas of the body dense with adipose tissue. A heightened suspicion for the disorder is therefore required in the case of penile calciphylaxis, given its unconventional location. The diagnosis of calciphylaxis is also challenging as the gold standard for diagnosis is biopsy which can often yield equivocal results. Unfortunately, in penile calciphylaxis, the utility of biopsies is further debated due to their potential to precipitate new lesions and their decreased sensitivity due to the limited depth of tissue that can be sampled. For these reasons, it is important that practitioners recognize other accessible and accurate investigative tools which can aid in their diagnosis. PRESENTING CONCERNS OF THE PATIENT We present the case of a 49-year-old man who presented to the emergency room with penile pain in the context of known chronic kidney disease secondary to diabetic nephropathy. The pain had been present for about a week, was exquisitely tender, and was initially associated with a faint violaceous lesion. This gentleman had just recently initiated peritoneal dialysis and had no other lesions on his body. DIAGNOSIS His pain was determined by ultrasound and plain radiograph to be secondary to calciphylaxis after two biopsies were nondiagnostic. INTERVENTIONS The patient had already made changes to his diet to reduce phosphate and calcium intake, and had been on phosphate-lowering therapy with both calcium and phosphate being within their respective target range. Following his diagnosis, this patient was promptly converted from peritoneal dialysis to hemodialysis with sodium thiosulphate and initiated hyperbaric oxygen therapy. This patient continues to be followed by nephrology and urology specialists.

Abstract
BACKGROUND Calciphylaxis is a rare disease, predominantly affecting patients with chronic kidney disease (CKD) and associated with significant morbidity and mortality due to progressive cutaneous calcification, necrotic ulceration and infection. Clinical registries have been established to better understand the risk factors, optimal treatments and disease outcomes of calciphylaxis. METHODS We established a prospective, Internet-based clinical registry for the online notification of calciphylaxis cases in Australia. Seven institutions participated, with data recorded on patient characteristics, biochemical parameters, treatments and disease outcomes. RESULTS Between 2014 and 2019, 47 cases of calciphylaxis were registered. The mean patient age was 66 ± 11 years and body mass index was 35 ± 9 kg/m2, with a higher proportion of females (51%). Eighty-seven percent of patients had end-stage kidney disease (ESKD), with 61% on hemodialysis or hemodiafiltration, with a median dialysis vintage of 4.8 [interquartile range (IQR) 1.7-7.4)] years. Five patients had CKD not requiring dialysis and two were kidney transplant recipients. Diabetes was present in 76% of patients and the cause of ESKD in 60%; 34% received vitamin K antagonists (VKAs) before diagnosis. The median parathyroid hormone level at diagnosis was 32 (IQR 14-50) pmol/L. The most common site of calciphylaxis was the lower limbs (63%), with 19% of patients having more than one area involved. Ten patients (22%) had a resolution of calciphylaxis and 25 died, with 50% mortality at a median of 1.6 (IQR 0.2-2.5) years from diagnosis. CONCLUSIONS The Australian Calciphylaxis Registry highlights risk factors for calciphylaxis, including diabetes, obesity and VKA use. Resolution of calciphylaxis is uncommon despite multimodal therapy and mortality from calciphylaxis in the first year following diagnosis remains high.

Abstract
Calciphylaxis is a cutaneous vasculopathy with high morbidity and mortality characterized by vascular intimal fibrosis, calcification, stenosis, thrombosis, and eventual tissue death due to ischemia. Histopathologic diagnosis is often difficult, frequently necessitating multiple tissues samples due to lack of specific histopathologic features and subtle changes on biopsies of early lesions. In this study, we review the reported clinical and histopathologic features of calciphylaxis, correlating them with relevant imaging, ancillary studies, and pathophysiology. Although many histopathologic changes seen in calciphylaxis are also reported in other conditions (eg, Mönckeberg sclerosis, lupus panniculitis, pancreatic panniculitis, and peripheral artery disease), calcification of subcutaneous small vessels, thrombosis and/or ischemic changes, pseudoxanthoma elasticum-like changes in the subcutis, and perieccrine calcification may serve as helpful clues. von Kossa and Alizarin red stains can assist in the identification of subtle calcification. Netlike calcification of the affected blood vessels on imaging further supports the diagnosis. Studies into the pathophysiology of calciphylaxis are ongoing and will hopefully facilitate the development of additional diagnostic adjuncts to increase sensitivity and specificity for the diagnosis of this disease.

Abstract
Calciphylaxis is a highly morbid disease that is strongly associated with chronic kidney disease (CKD); however, the histologic criteria for diagnosis have not been well established nor have their specificity for calciphylaxis been determined. This retrospective study aimed to examine the prevalence of histologic features commonly associated with calciphylaxis in noncalciphylaxis patients. We also sought to evaluate whether these features may be more prevalent in patients with CKD. To assess this, healthy marginal skin tissue from above-the-knee amputation specimens was compared between patients with CKD (n = 23) and without CKD (n = 47). Intravascular calcification of capillaries or small-to-medium arterioles was detected on von Kossa stain in 40.0% of the entire cohort. Capillary calcification and intravascular thrombosis were more prevalent in patients with CKD. Finely stippled capillary calcification was present in 26.1% of patients with CKD versus 8.5% of patients without CKD (P = 0.0484), and intravascular thrombosis was present in 8.7% of patients with CKD and 0.0% of patients without CKD (P = 0.0403). None of the patients in this study had clinical evidence of calciphylaxis at presentation and in at least a 1-year follow-up period. This study confirms that the histologic features previously associated with calciphylaxis are nonspecific and are more prevalent in patients with CKD.

Abstract
Calcific uremic arteriolopathy (CUA), also known as calciphylaxis, is a complex syndrome of deranged mineral metabolism and vascular calcification leading to tissue ischemia that primarily occurs in end-stage renal disease (ESRD) patients on maintenance hemodialysis (HD). We report a case illustrating a temporal relationship between long-term warfarin anticoagulation and development of CUA in a patient with pre-dialysis chronic kidney disease (CKD) who progressed to ESRD. Serial <sup>99m</sup>Tc-methylene diphosphonate bone scintigraphy documented the evolution of metastatic CUA over a 5-month period following HD initiation. Given the temporality demonstrated here via imaging, we speculate that warfarin's influence on vitamin K-dependent matrix Gla protein function coupled with risk factors associated with ESRD led to the development of metastatic CUA.

Abstract
Materials and Methods 24 patients with CUA and on RRT were evaluated at Detroit Medical Center from 2007 to 2016. Skin biopsy was used in almost all patients, along with the radiological and clinical findings. The patient's clinical and paraclinical data were retrieved from the electronic medical records. The effect of treatment modalities and the underlying hyperparathyroidism management were compared to the clinical outcomes using appropriate statistical tests. Results Twenty-one patients were on hemodialysis, two patients received renal transplants, and one patient was on peritoneal dialysis. Diabetes mellitus was the most prevalent cause of ESRD. The parathyroid hormone level (PTH) was elevated in 22 patients. Fifteen patients were diagnosed 2 weeks or more prior to skin lesion onset. Twenty-two and thirteen patients received sodium thiosulphate and cinacalcet, respectively. Patients with lower PTH and the calcium-phosphate product levels had a relatively better outcome of CUA. Conclusions A multifaceted approach may play a role in treating CUA. Referral to a nephrologist may aid in the early diagnosis and prompt management of CUA.

Abstract
Intramuscular injections of paraffin oil can cause foreign body granuloma formation and hypercalcemia. Macrophages with the ability to produce high levels of 1,25(OH)2 D3 may induce the mineral disturbance, but no major series of patients have been published to date. Here, medical history, physical evaluation, biochemical, and urinary analysis for calcium homeostasis were obtained from 88 males, who 6 years previously had injected paraffin or synthol oil into skeletal muscle. Moreover, granuloma tissue from three men was cultured for 48 hours ex vivo to determine 1,25(OH)2 D3 production supported by qPCR and immunohistochemistry of vitamin D metabolism and immune cell populations after treatment with 14 different drugs. The 88 men were stratified into men with hypercalcemia (34%), whereas normocalcemic men were separated into men with either normal (42%) or suppressed parathyroid hormone (PTH) (24%). All men had high calcium excretion, and nephrolithiasis was found in 48% of hypercalcemic men, 22% of normocalcemic men with normal PTH, and 47% of normocalcemic men with suppressed PTH. Risk factors for developing hypercalcemia were oil volume injected, injection of heated oil, high serum interleukin-2 receptor levels, and high urine calcium. High 1,25(OH)2 D3 /25OHD ratio, calcium excretion, and low PTH was associated with nephrolithiasis. The vitamin D activating enzyme CYP27B1 was markedly expressed in granuloma tissue, and 1,25(OH)2 D3 was released in concentrations corresponding to 40% to 50% of the production by human kidney specimens. Dexamethasone, ketoconazole, and ciclosporin significantly suppressed granulomatous production of 1,25(OH)2 D3 . In conclusion, this study shows that injection of large oil volumes alters calcium homeostasis and increases the risk of nephrolithiasis. Hypercalciuria is an early sign of disease, and high granulomatous 1,25(OH)2 D3 production is part of the cause. Prospective clinical trials are needed to determine if ciclosporin, ketoconazole, or other drugs can be used as prednisolone-sparing treatment. © 2020 American Society for Bone and Mineral Research (ASBMR).

Abstract
Calciphylaxis is a deadly disease that is currently diagnosed through a skin biopsy of resultant necrotic lesions despite many cases lacking this characteristic finding. Recently, research has demonstrated the ability of various radiologic techniques to detect calciphylaxis and have promoted their capabilities in earlier diagnosis without tissue invasion. In this case, an obese 55-year-old female with end stage renal disease, and a long history of dialysis, complained of weeks of persistent abdominal pain that was accompanied by a mottled, lacey, net-like rash that resembled livedo reticularis. Computed tomography of the abdomen revealed extensive arterial calcification and subcutaneous calcium deposition. These radiologic findings, coupled to a high clinical suspicion, prompted treatment for suspected calciphylaxis. Remarkably, after 1 week the patient reported substantial improvement. Hopefully, this publication in conjunction with previous and future research will raise awareness on the role Radiologists can play in expediting the diagnostic process for a lethal disease, especially when a tissue biopsy is not a feasible option.

Abstract
Calciphylaxis is a rare but highly fatal vascular calcification disorder with a predilection for patients with end stage renal disease (ESRD). The pathogenesis of calciphylaxis is unknown, however, several risk factors have been identified such as hypercalcemia, hyperphosphatemia, hyperparathyroidism, low serum albumin, and history of warfarin therapy. This article presents a case of calciphylaxis induced by warfarin in a COVID-19 patient.

Abstract
Calciphylaxis is a poorly understood disease with high morbidity and mortality. The current primary literature on treatment is lacking; however, disease management often involves a multifaceted approach with a primary focus on consistent wound care. This report describes a case outlining the long-term management of nonuremic calciphylaxis wounds in a patient with severe malnutrition with the use of human amniotic membrane grafts, aggressive surgical debridement, nutritional therapy, and advanced wound healing techniques. A 38-year-old African American female with a history of non-uremic calciphylaxis presented from a transitional facility with numerous non-healing wounds in the setting of severe malnutrition secondary to bariatric surgery. Biweekly wound debridement was initiated utilizing an amniotic stem cell skin graft, dry applicable absorbent dressing, high-frequency ultrasonic ablation, and wound vacuum-assisted closure (VAC) over the course of approximately nine months. Nutritional supplementation was given in the form of jejunostomy tube feed due to a gastric bypass and a perforated viscus. At the current date, the patient demonstrates significant improvement in pain and wound healing. The patient is also able to ambulate with care and has begun steps towards independent management of wounds. Future goals of care include independent bedside wound management, placement of allograft, and discharge to a long-term care facility. Most patients with refractory pain, widespread necrotic wounds, and dangerous comorbidities will inevitably be referred to palliative care. This case creates a framework for the long term management of medically complex patients with nonuremic calciphylaxis using human amniotic membrane stem cell grafts and appropriate advanced wound care techniques.

Abstract
Calciphylaxis is a deadly, painful disease with a 1-year mortality of up to 50%. The disease is commonly associated with patients with end-stage kidney disease (ESKD), but it can manifest in non-uremic patients as well. In patients who are undergoing dialysis, the incidence of calciphylaxis can range from 0.04% to 4%. The progressive arterial calcification seen in calciphylaxis can affect multiple body organs, including the skin, brain, lungs, and muscle. In cutaneous calciphylaxis, painful and non-healing nodules, plaques, and ulcers may appear, increasing morbidity for patients. Diagnosis can be difficult, and the condition can clinically appear similar to other dermatological diseases, especially in non-uremic patients. Currently, skin biopsy with histological analysis is the most reliable method to help diagnose the condition. In certain cases, the use of medical imaging may be helpful. Treatment of pain in this condition can be difficult and should be multimodal and include wound care as well as modification of risk factors. Analgesic options include opioids, nonsteroidal anti-inflammatory drugs (NSAIDs), as well as analgesic options that are targeted for specific patients. There are currently multiple clinical trials underway that are studying targeted therapies for this condition.

Abstract
Calciphylaxis is a rare and severe condition, characterized by calcification and thrombosis of small vessels, mainly affecting the skin. It is most often described in patients with end-stage renal disease on dialysis. Rarer cases of non-uremic calciphylaxis are reported. The prognosis is grim and the treatment is not well codified. Sodium thiosulfate has been used for more than a decade in the treatment of uremic calciphylaxis and has been shown to be effective. Its use in non-uremic cases has been reported in a few rare observations. Rheopheresis is a technique very recently used as an adjuvant treatment in uremic calciphylaxis. We describe a case of non-uremic calciphylaxis in a patient with normal renal function and with calcium supplementation. Sodium thiosulfate was introduced, then discontinued due to the patient's poor tolerance for this treatment. Rheopheresis was then used and allowed the acceleration of healing process and a significant reduction in pain. These two treatments are promising, larger studies are needed to establish their effectiveness in non-uremic calciphylaxis.
