Insights
Calciphylaxis, or calcific uremic arteriolopathy, is a rare condition often seen in dialysis patients. This case highlights its occurrence in earlier kidney disease stages, emphasizing prompt diagnosis for better outcomes.
Area of Science:
- Nephrology
- Dermatology
- Vascular Biology
Background:
- Calciphylaxis, also known as calcific uremic arteriolopathy (CUA), is a rare and severe cutaneous disease.
- It predominantly affects patients with advanced chronic kidney disease (CKD) undergoing long-term hemodialysis.
Observation:
- A case report of a 61-year-old female patient with worsening CKD not yet on dialysis is presented.
- The patient exhibited severe, progressive calciphylaxis affecting both lower limbs.
Findings:
- Calcific uremic arteriolopathy is a rare, fatal condition necessitating prompt diagnosis and treatment.
- While classically associated with end-stage kidney disease and renal replacement therapy, CUA can manifest in earlier stages of kidney disease.
Implications:
- Non-uremic calciphylaxis should be considered in patients with earlier CKD stages, particularly those with co-morbidities.
- Early suspicion and diagnosis are crucial to mitigate the high morbidity and mortality risks associated with calciphylaxis.
Abstract:
BACKGROUND Calciphylaxis is a rare cutaneous disease, also known as calcific uremic arteriolopathy, that occurs most frequently in patients with advanced chronic kidney disease and on long-term hemodialysis. CASE REPORT We describe the case of a 61-year-old female patient with worsening chronic kidney disease not on dialysis therapy, who presented with severe progressive calciphylaxis on both lower limbs. CONCLUSIONS Calcific uremic arteriolopathy is a rare fatal condition that requires prompt diagnosis and treatment. It is classically described in patients with end-stage kidney disease on long-term renal replacement therapy but can present in patients with an earlier stage of kidney disease. Non-uremic calciphylaxis should be suspected in patients with earlier stages of kidney disease, especially in those with other concurrent risk factors or co-morbid conditions, to avoid the high risk of morbidity and mortality associated with such cases.
