1/20. calciphylaxis in moderate renal insufficiency: changing disease concepts.calciphylaxis is a rare but frequently fatal complication in patients with end-stage renal disease. Original concepts regarding groups at risk for the disease, predisposing factors, and associated morbidity have changed significantly in the past few years as more cases are reported. We present a patient who developed fatal calciphylaxis in the setting of moderate renal insufficiency to illustrate some of the evolving concepts in this disease process.- - - - - - - - - - ranking = 1keywords = calciphylaxis (Clic here for more details about this article) |
2/20. calciphylaxis in the absence of renal failure.We report a patient with severe bilateral leg ulceration that was resistant to treatment. A biopsy confirmed the cause as calciphylaxis. calciphylaxis refers to a syndrome of calcium deposition in the small and intermediate dermal vasculature which can lead to epidermal ischaemia, ulceration and necrosis. Most cases occur in those with chronic renal failure and secondary hyperparathyroidism. We describe the rare presentation of calciphylaxis in a patient with normal renal function and primary hyperparathyroidism who had many classical features. Unfortunately she developed gangrene, sepsis and died.- - - - - - - - - - ranking = 2keywords = calciphylaxis (Clic here for more details about this article) |
3/20. calciphylaxis in a patient without renal failure or elevated parathyroid hormone: possible aetiological role of chemotherapy.calciphylaxis is a rare, often fatal disease characterized clinically by progressive cutaneous necrosis and ulceration, and histologically by vascular calcification and thrombosis. It has been described in association with end-stage renal disease, after initiation of dialysis, following renal transplantation, and in patients with hyperparathyroidism. We present the first case of calciphylaxis occurring in a patient with both normal renal function and parathyroid hormone level and discuss the possible aetiological role of chemotherapy-induced functional protein C and protein s deficiency.- - - - - - - - - - ranking = 1keywords = calciphylaxis (Clic here for more details about this article) |
4/20. calciphylaxis associated with cholangiocarcinoma treated with low-molecular-weight heparin and vitamin K.calciphylaxis is a rare disorder of small-vessel calcification and cutaneous infarction associated with chronic renal failure. Rare cases of calciphylaxis not associated with chronic renal failure have been reported with breast cancer, hyperparathyroidism, and alcoholic cirrhosis. To our knowledge, we report the first case of calciphylaxis without chronic renal failure associated with cholangiocarcinoma and the first attempt to treat calciphylaxis with vitamin K. A 56-year-old woman presented with necrotic leg ulceration. She was treated initially with low-molecular-weight heparin, with no effect. A coagulation work-up showed vitamin k deficiency. During vitamin K therapy, the patient had fulminant progression of the calciphylaxis. She died, and an autopsy showed metastatic cholangiocarcinoma. thrombosis and protein c deficiency have been implicated in the pathophysiology of calciphylaxis. Functional protein c deficiency may be one of several factors contributing to the development of calciphylaxis. Vitamin K therapy was ineffective in our patient and may have been detrimental.- - - - - - - - - - ranking = 6keywords = calciphylaxis (Clic here for more details about this article) |
5/20. calciphylaxis, a poorly understood clinical syndrome: three case reports and a review of the literature.Systemic calcification syndromes are a recognized complication occurring in some patients with end-stage renal disease (ESRD) and secondary hyperparathyroidism. These patients develop severe livedo reticularis and subcutaneous tissue lesions progressing to frank necrosis and ultimately large areas of eschar. Clinically this syndrome is known as calciphylaxis; these lesions are usually resistant to aggressive debridement, systemic antibiotics, and revascularization procedures. We report three patients with somewhat different clinical presentations but all sharing a common link of exquisitely painful leg ulcers initially being treated as ischemic lesions or venous stasis-type ulcerations. These three patients were diagnosed with calciphylaxis on the basis of clinical, biochemical, and histopathological criteria. Two patients underwent parathyroidectomy late in the progression of their disease, with some resolution of their ulcerative lesions.- - - - - - - - - - ranking = 2keywords = calciphylaxis (Clic here for more details about this article) |
6/20. Necrotic skin lesions in a dialysis patient: a multifactorial entity.A female dialysis patient with a consistently high serum calcium phosphate product presented with large necrotic skin lesions with ulcers. The clinical course was highly suggestive of calciphylaxis. parathyroidectomy was followed by the healing of the lesions. New skin lesions appeared following relapse of hyperparathyroidism. Her clinical records included a long past of hypertension, which was the cause of her renal failure. She had a limited walking range and previously had presented bilateral ulcers of vascular origin. This case presents a type of lesion which bears a serious prognosis in dialysis patients. The clinical context and the presentation of the lesions are compatible with multiple etiology: vascular lesions and calciphylaxis. The documented longitudinal follow-up illustrates the importance of treating the different factors known to participate in the appearance of skin lesions in dialysis patients. Particularly, it stresses the benefit of performing parathyroidectomy, even if the parathyroid hormone level is not in the range normally accepted as requiring surgical removal of parathyroid glands.- - - - - - - - - - ranking = 2keywords = calciphylaxis (Clic here for more details about this article) |
7/20. Idiopathic calciphylaxis.A 68-year-old woman presented with a painful necrotic ulcer on her right calf and necrotic breakdown of a left below-knee amputation stump as a result of calciphylaxis. No cause could be identified and corrected. Treatment comprised wound care, substituting low molecular weight heparin for warfarin, hyperbaric oxygenation and etidronate disodium, none of which were helpful and major limb amputations were considered the best option for this patient.- - - - - - - - - - ranking = 5keywords = calciphylaxis (Clic here for more details about this article) |
8/20. Painful ulcers in calciphylaxis - combined treatment with maggot therapy and oral pentoxyfillin.BACKGROUND: calciphylaxis is a rare syndrome developing predominantly in female patients suffering from end-stage renal disease (ESRD) with secondary hyperparathyroidism. skin lesions begin as superficial patches that quickly progress to painful necrotic ulcers. Histopathological findings are calcification of small arteries and arterioles and infarction of subcutis and skin. The prognosis of calciphylaxis is poor due to an increased risk of systemic infection. methods: We report on a 50-year-old woman suffering from calciphylaxis. Initial treatments were not tolerated due to pain and therefore the patient was treated with maggot therapy and 800 mg/day of oral pentoxyfillin. RESULTS: Over a period of 6 months a complete remission of her skin lesions was achieved. CONCLUSION: patients suffering from ulcers due to calciphylaxis may benefit from the use of maggot therapy, which cleanses ulcers and prevents systemic infection.- - - - - - - - - - ranking = 7keywords = calciphylaxis (Clic here for more details about this article) |
9/20. Distal calcific uremic arteriolopathy in a hemodialysis patient responds to lowering of Ca x P product and aggressive wound care.Calcific uremic arteriolopathy (CUA; calciphylaxis), is reported in approximately 4% of patients receiving hemodialysis, and is characterized by skin lesions that may include firm plaques or subcutaneous nodules. The syndrome has been associated with the use of calcium-containing phosphate binders, high serum phosphorus levels, and elevated calcium x phosphorus (Ca x P) product. This report describes a 73-year-old white male with chronic renal failure due to diabetes mellitus and hypertension, who had been on home hemodialysis for 3 years. He developed CUA after an acute elevation in serum phosphorus (8.1 mg/dl) and Ca x P product (84.2), with painful skin lesions that rapidly progressed to become circumferentially located around the entire lower left extremity. The patient declined amputation, opting for a treatment approach that included aggressive management of phosphorus and calcium, more frequent dialysis, and rigorous wound care. All calcium-containing phosphate binders were discontinued. The patient was switched from calcitriol to paricalcitol, a less calcemic form ofvitamin D replacement therapy, from which he was slowly weaned. dialysis dose and frequency was also increased to 4 hours, 6 times weekly. The patient was given sevelamer hydrochloride (Renagel)--a calcium-free phosphate binder--with meals at an initial dose of 6.4 g/day. After 5 months, the dose was increased to 8 g/day, with additional dietary counseling to restrict phosphorus intake. At this point, serum phosphorus decreased to 4.9 mg/dl and calcium levels had fallen to 8.5 mg/dl, compared to 9.5 - 10.4 mg/dl prior to diagnosis of CUA with an overall decline in the Ca x P product. Significant healing of the lesions was noted at 8 months following diagnosis, with near-total healing by 12 months. Our studies support that lowering of elevated serum phosphorus, calcium, and Ca x P product, together with aggressive wound care may contribute to the successful outcome of patients with CUA.- - - - - - - - - - ranking = 1keywords = calciphylaxis (Clic here for more details about this article) |
10/20. calciphylaxis in a patient with alcoholic liver disease in the absence of renal failure.calciphylaxis is a rare, potentially life-threatening syndrome characterized by progressive microvascular and superficial soft tissue calcification, usually seen in patients with chronic renal failure. We describe an unusual case of calciphylaxis in a patient with alcoholic liver disease and normal renal function who responded well to conservative wound care.- - - - - - - - - - ranking = 1keywords = calciphylaxis (Clic here for more details about this article) |
