ABSTRACT

PURPOSE: To perform a systematic review of case reports and case series to investigate risk factors, treatment modalities, and the outcome of penile calciphylaxis. METHOD: We performed a systematic search of the MEDLINE and Scopus databases to identify case reports or case series of penile calciphylaxis. The patient characteristics, laboratory investigations, diagnostic modalities, treatment modalities, and outcomes were extracted. We compared clinical characteristics and treatment between patients who survived or demised and between patients with clinical improvement and those without to identify the poor prognostic risk factors. RESULTS: Ninety-four articles were included from 86 case reports and 8 case series with 121 patients. Most of the patients were on hemodialysis (78.9%). The median time since starting dialysis was 48 months (24-96 months). Sodium thiosulfate was used to treat penile calciphylaxis in 23.6%. For surgical management, partial or total penectomy was performed in 45.5% of the patients. There was no association between sodium thiosulfate use, partial or total penectomy, and improvement in clinical outcomes. The mortality rate in patients with penile calciphylaxis was 47.8% and the median time to death was 3 months (0.75-9 months). The presence of extragenital involvement was significantly related to mortality (p = 0.03). CONCLUSION: A calcified penile artery results in penile calciphylaxis, a rare vascular phenomenon associated with high morbidity and mortality. Management of penile calciphylaxis includes the medical management of risk factors, surgical debridement, or penectomy. Therefore, early prevention and diagnosis as well as immediate appropriate treatment are needed.

ABSTRACT

Calciphylaxis is a debilitating disease associated with high mortality and morbidity secondary to pain, nonhealing wounds and frequent hospital admissions. We qualitatively assessed the burden of calciphylaxis on patient quality of life through semi-structured interviews with nine adult participants. Participants identified an inability to complete activities of daily living because of mobility impairment and decreased strength, although most denied complete dependence on others. All participants described pain as the worst aspect of disease, citing a variable course, unpredictability in severity and poor control despite medical therapy. Calciphylaxis also caused feelings of sadness and anger, having a negative impact on self-confidence. Supportive care needs to address the pervasive and severe nature of pain, mobility impairment and psychiatric comorbidities; such interventions may decrease the overall burden for patients with calciphylaxis.

ABSTRACT

Calciphylaxis, also known as calcific uremic arteriopathy, is a rare calcification syndrome that presents as ischemic skin necrosis and severe pain. It has a high mortality rate and is characterised by calcification of the small and medium arteries and micro-thrombosis. Calciphylaxis mainly occurs in patients with end-stage renal disease. In recent years, there have been an increasing number of cases of calciphylaxis associated with connective tissue diseases. Given the absence of clear diagnostic criteria for calciphylaxis thus far, an early diagnosis is crucial for designing an effective multidisciplinary treatment plan. In this article, we review the research progress on calciphylaxis and describe its characteristics in the context of connective tissue diseases.

ABSTRACT

In the present case of a 56-year-old male, hemodialysis was introduced from December 20XX-2 due to chronic renal failure caused by diabetic nephropathy. In February 20XX, a glans penis ulcer was observed. It gradually expanded. Angiography conducted in April revealed complete occlusion of the left internal pudendal artery and poor visualization of the bilateral penile arteries. Given the high risk of obstruction, endovascular treatment was not conducted. The glans penis ulcer continued to expand, and maintenance dialysis became difficult due to intractable pain. Opioids were introduced, but the pain could not be controlled. In May 20XX, the patient was referred to our department for surgical treatment, and partial penile resection was performed. The patient was diagnosed with penile calciphylaxis based on clinical findings and pathological diagnosis. After the surgery, the pain subsided considerably, and the patient is being followed on an out-patient basis.

ABSTRACT

OBJECTIVES: Calcium depositions are frequent in multiple inflammatory dermatosis, they can be explored by ultrasound (US) but the patterns of these depositions have not yet been described. The aim of this study is to describe different patterns of calcium deposition in inflammatory dermatoses. METHODS: The clinical and US data of 58 patients from 7 different centers with inflammatory dermatosis showing ultrasonography-detected calcium depositions was retrospectively reviewed. RESULTS: Dystrophic calcinosis represented 86.2%, calciphylaxis 8.6%, and metastatic calcinosis 5.2%. Three different sonographic patterns of calcium deposition were found: 1) thin hyperechoic bands, parallel to the surface of the epidermis, generating a strong and wide posterior acoustic shadow; 2) hyperechoic spots or lumps with a narrow acoustic shadow; and 3) a linear hyperechoic band parallel to the walls of a blood vessel with also a narrow acoustic shadow. The predominant pattern in metastatic calcifications was type 1, in dystrophic calcifications type 2, and in calciphylaxis type 3. In dystrophic calcinosis, cutis deposits were longer and wider than in calciphylaxis (P < .05). CONCLUSION: New data on inflammatory dermatoses with calcium deposition may be useful for the diagnosis and monitoring of calcium deposits and could avoid the performance of more invasive tests, such as a skin biopsy.

ABSTRACT

BACKGROUND: Calciphylaxis is a rare thrombotic vasculopathy characterized by high morbidity and mortality. There is a paucity of studies examining longitudinal outcomes. OBJECTIVE: To assess mortality, days spent in the hospital, and amputations in patients with calciphylaxis. METHODS: A retrospective medical record review was conducted in 145 patients diagnosed with calciphylaxis at an urban tertiary care hospital from January 2006 to December 2018. RESULTS: Six-month mortality was 37.2%, and 1-year mortality was 44.1%. Patients with nephrogenic calciphylaxis had worse survival than those with nonnephrogenic calciphylaxis (P = .007). This difference in survival disappeared when limiting mortality to deaths due to calciphylaxis. Age (P = .003) and end-stage renal disease (P = .01) were risk factors associated with 1-year mortality. Diabetes mellitus was associated with greater total hospitalization days (coefficient, 1.1; 95% confidence interval, 1.01-1.4); bedside debridement was associated with fewer hospitalization days (coefficient, 0.8; 95% confidence interval, 0.7-0.9). Amputations were not associated with any of the examined risk factors. The use of warfarin followed by a transition to nonwarfarin anticoagulation was associated with decreased hazard of death (P = .01). LIMITATIONS: Retrospective nature. CONCLUSIONS: Calciphylaxis remains a complex, heterogeneous disease. Mortality is lower in patients with nonnephrogenic disease. These findings may be incorporated during discussions regarding the goals of care to facilitate informed shared decision making.

ABSTRACT

ABSTRACT: A 72-year-old woman with membranous glomerulonephritis and failed renal transplant on peritoneal dialysis presented with bilateral vision loss. She reported several months of diminishing right eye vision that worsened after cataract extraction. On presentation, visual acuity was hand motion in the right and 20/100 in the left eye with a right afferent pupillary defect. Confrontation visual fields were constricted bilaterally. Intraocular pressure was 23 in the right eye, and there was diffuse right eye central corneal opacity with iris neovascularization. Fundus examination revealed bilateral pale optic nerves with cotton wool spot inferior to the left optic disc and diffuse arteriolar whitening with crystalline deposits in the left macula. Given fundus appearance, concurrent ischemic optic neuropathy, and ocular ischemic syndrome, ocular calciphylaxis was suspected. The patient reported development of painful gluteal nodules a month prior, and biopsy revealed calcinosis cutis, a dermatopathologic finding on the spectrum of calcific vasculitides. Her vision continued to decline in both eyes with left eye vision of 20/400. Intravenous sodium thiosulfate through hemodialysis was started with initial improvement in left eye vision to 20/125, but subsequently declined despite treatment. Pathogenesis of systemic calciphylaxis is poorly understood but believed to result from upregulation of osteogenesis and decreased inhibition of vascular calcification in parathyroid axis dyscrasias due to end-stage renal disease. Excess serum calcium-phosphate deposits in blood vessels causing tissue infarction, most commonly in the skin. Prior case reports have described ischemic optic neuropathy mimicking giant cell arteritis and crystalline retinopathy with ocular ischemic syndrome separately. Treatment with empiric intravenous sodium thiosulfate and calcium chelation may preserve vision in some patients.

Title: Cutaneous calciphylaxis of the glans penis presenting as a gangrenous ulceration Authors: Marie Danset, Cécile Lesort, Denis Jullien, Jean Kanitakis Affiliations: Dermatology Department, Edouard Herriot Hospital, Hospices Civils de Lyon, Claude Bernard Lyon I University, Lyon, France Corresponding Author: Jean Kanitakis, Department of Dermatology, Edouard Herriot Hospital Group, 69437 Lyon Cedex 03, France, Tel: 33-472110301, Email: jean.kanitakis@univ-lyon1.fr Abstract: Calciphylaxis is a rare microvascular disorder causing necrotic skin ulcers. It is characterized by deposits of calcium within vascular walls but its precise pathogenesis remains poorly understood. A major risk factor is end-stage renal disease on dialysis. We report a 67-year-old man with calciphylaxis revealed by an unusual necrotic ulcer of the glans penis. The patient also presented with bilateral panniculitis of the thighs and a calf ulcer. All those lesions were painful, highlighting the value of pain as a diagnostic clue. Penile involvement of calciphylaxis is rare and biopsy is often avoided in this area. However, rapid diagnosis of calciphylaxis is important because early treatment has a better chance of being successful. Our patient's condition deteriorated rapidly with development of bilateral retinal artery occlusion and he died shortly thereafter. This case further highlights the fact that calciphylaxis is a systemic vascular disease with an ominous prognosis.

ABSTRACT

Calciphylaxis, a rare disease mainly seen in patients with chronic kidney disease, is characterised by ischaemic skin damages and excruciating pain. Calciphylaxis has poor prognosis which often results in amputation and high mortality. Although guidelines for the management of calciphylaxis are not available, sodium thiosulfate has shown efficacy in many clinical reports. We report the case of a 64-year-old advanced calciphylaxis male patient who had two amputations due to intolerable pain manifested as deteriorating ulcer. After he was treated with intravenous sodium thiosulfate (STS), his pain was significantly relieved with a healing trend of the big wound. One more amputation for the remission of intractable pain was avoided. The treatment experience indicates that sodium thiosulfate is of great value in quick pain relief and reducing suffering of calciphylaxis patients.

ABSTRACT

In this article we focus on updates in select etiologies of retiform purpura. These causes of retiform purpura, in addition to bacterial or fungal sepsis, disseminated intravascular coagulation, purpura fulminans, and catastrophic antiphospholipid syndrome, are important diagnoses with potential for morbidity and mortality. Important aspects in the pathophysiology, patient demographics and risk factors, updates in the diagnostic workup, histopathology, and treatment of these specific conditions are discussed.

ABSTRACT

While initial reports regarding coronavirus disease 2019 (COVID-19) focused on its pulmonary manifestations, more recent literature describes multisystem abnormalities related to its associated microvascular angiopathy. Calciphylaxis is a rare systemic condition characterized by tissue necrosis in the setting of systemic microvascular calcifications. Both COVID-19 and calciphylaxis are procoagulant diagnoses associated with vascular-mediated cutaneous findings. To our knowledge, this is the first report to document the coexistence of COVID-19 associated retiform thrombotic purpura and calciphylaxis in a single patient, to link the pathologic etiologies of the two entities, and to describe the concomitant diagnoses' associated radiologic findings.

ABSTRACT

Non-uremic calciphylaxis is a rare, life-threatening condition characterized clinically by cutaneous necrosis and histologically by calcium deposition in small vessel walls. The etiology of non-uremic calciphylaxis remains the subject of ongoing speculation and debate. Herein we present a patient with calciphylaxis who had normal kidney function and numerous rheumatologic diseases, namely systemic lupus erythematosus (SLE), Sjogren syndrome (SS), and myasthenia gravis (MG). We review the pathophysiology, possible mechanisms, and management for non-uremic calciphylaxis.

ABSTRACT

Calcific uremic arteriolopathy (CUA) or calciphylaxis is a syndrome characterized by calcification of vessels located in the dermis and adipose tissue. It commonly occurs in patients with diabetes mellitus, hypertension, and end-stage renal disease. Clinical presentation generally begins with severe pain, followed by the presence of liveloid or purpuric plaques. Later the formation necrotic ulcers occur. This condition is associated with a poor prognosis, with a high rate of mortality within months of the diagnosis. Penile involvement is an uncommon but severe manifestation. We present an 81-year-old man with a history of diabetes mellitus, hypertension, and end-stage renal disease with a one-month evolution of painful necrotic ulcers on his glans penis. He was diagnosed with CUA. Owing to infection complicated by sepsis; penectomy was performed. Unfortunately, the patient died of myocardial infarction during his hospitalization.

ABSTRACT

We present a case of a 68-year-old man with calciphylaxis, who was found to have a floating thrombus in the descending aorta on a transesophageal echocardiogram. The use of 3D echocardiography demonstrated nicely the free motion of the thrombus, emerging from an atherosclerotic plaque in the descending aorta. Anticoagulation was started for thromboembolism prevention.

ABSTRACT

A 72-year-old woman experienced anterior ischemic optic neuropathy in her left eye. The funduscopic and fluorescein angiographic findings were strongly suggestive of giant cell arteritis. Temporal artery biopsy revealed extensive calcification in the vessel wall consistent with calciphylaxis. This unusual disorder should be considered in the differential diagnosis of anterior ischemic optic neuropathy, particularly the arteritic form.

ABSTRACT

BACKGROUND: Calciphylaxis is a well-known entity in end-stage kidney disease and after renal transplant. Cases of nonuremic calciphylaxis (NUC) have also been reported, but data on this rare condition are mainly empirical. OBJECTIVE: We discuss a case of NUC secondary to spontaneous tumour lysis syndrome in a patient who had chemotherapy for non-Hodgkin lymphoma and present a review of the literature to better characterize malignancy-associated NUC. METHODS: We identified 12 published cases of malignancy-associated NUC. RESULTS: This systematic review of malignancy-associated NUC did not show a relationship between the type of malignancy, the distribution of skin lesions, or mortality. However, distal more than proximal involvement seems to be more frequently associated with calcium phosphate imbalance. CONCLUSION: Clinicians must maintain a high index of suspicion for calciphylaxis when evaluating patients with cutaneous lesions developed in the setting of malignancy.

ABSTRACT

BACKGROUND: Calciphylaxis, also called calcific uremic arteriolopathy, is a highly morbid syndrome characterized by calcium deposition and occlusion of small arterial vessels of the dermis and subdermal adipose tissue, leading to necrosis and gangrene. Penile involvement is rare and its management presents considerable challenges. CASE: We review the case of a 47-year-old man with end-stage renal disease managed with hemodialysis, diabetes mellitus, and urinary incontinence who presented with a painful necrotic lesion on his glans penis, and the second and third toes of his right foot. Following diagnosis of calciphylaxis of the toes and penis, he was conservatively managed with topical wound care, sodium thiosulfate adjustment of hemodialysis, and phosphate binder medications. Over the course of 2 months, his wound worsened in the setting of continued urinary incontinence, and before planned diversion with a suprapubic catheter, he progressed to gangrene and sepsis. After a goals-of-care discussion with the patient and family, he elected to forego debridement and was discharged on home-based palliative care. CONCLUSIONS: Penile calciphylaxis is a rare, life-threatening disease that portends a poor prognosis. Conservative principles for management include normalization of calcium phosphate levels and local wound care. Penectomy may not impact survival. Ultimately, each case is individualized, and we encourage establishing goals of care in collaborative discussion with an interdisciplinary care team, patient, and family.

ABSTRACT

A 62-year-old man was referred to the emergency department of our hospital with pain and swelling in the left mandibular region that had evolved over the previous 2 months (Figure 1). His medical history included nonuremic calciphylaxis and systemic sclerosis (Figure 2). Since the diagnosis of the nonuremic calciphylaxis 5 years before, the patient had been treated with intravenous (IV) sodium pamidronate 60 mg per week for 11 months, without improvement, followed by IV sodium thiosulfate 25 mg twice a week for 18 month. During year 3 of treatment, the calciphylaxis lesions reappeared, and IV sodium pamidronate 60 mg per week was reintroduced to the patient's treatment. The patient remained with double treatment for the next 2 years, but 3 months before the patient's presentation, the IV treatment had been suspended due to an absence of peripheral venous access.

ABSTRACT

INTRODUCTION: Patients with renal failure who are being treated with dialysis frequently develop neuromuscular manifestations. Renal failure-associated calciphylaxis, also termed calcific uremic arteriolopathy (CUA), is a life-threatening condition usually observed in patients with end-stage renal disease on chronic dialysis or after renal transplantation. METHODS: We describe a hemodialyzed patient who presented with rapidly progressive unexplained systemic vasculopathy, muscle atrophy, and proximal weakness, that unexpectedly proved to be caused by calciphylaxis. RESULTS: Quadriceps muscle biopsy disclosed diffuse vascular calcific deposits on medium- and small-sized vessels, characteristic of CUA. Other changes included ischemic myopathy, focal intracellular calcium accumulation within myofibers, and calcium deposits in endomysial capillaries associated with marked complement activation and C5b9 formation. CONCLUSION: There are only a few descriptions of muscle involvement in the context of CUA, a condition with a prognosis that depends on early diagnosis and treatment. This report underscores the usefulness of muscle biopsy in the diagnosis of systemic calciphylaxis. Muscle Nerve 56: 529-533, 2017.

ABSTRACT

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. Vascular calcification was compared in skin biopsy specimens and radiology images. RESULTS: Seven patients were identified. Small-vessel calcification as fine as 0.1 to 0.3 mm was identified on plain films in 3 patients; 0.1 to 0.2 mm by mammography in 3 patients, and 0.1 to 0.2 mm by computed tomography imaging in 1 patient, nearly as fine a resolution as on histopathology. LIMITATIONS: This was a single-center study with limited sample size. CONCLUSION: Radiologic imaging might enable more rapid diagnosis of calciphylaxis when skin biopsy specimen is pending or not available.
