Resistant Hypercalcemia in Peritoneal DialysisUnveiling the Role of Vitamin A Toxicity

Introduction
Hypercalcemia remains a significant challenge in end-stage renal disease (ESRD) patients undergoing dialysis. A recent case study published in The Journal of Clinical Nephrology highlights an unusual case of resistant hypercalcemia linked to chronic Vitamin A toxicity. Understanding such rare complications can aid in better management strategies. Visit https://www.clinnephrologyjournal.com/jcn for more groundbreaking research in this field.

Case Summary: A Rare Diagnosis of Vitamin A Toxicity
A 44-year-old male ESRD patient on peritoneal dialysis was admitted with acute hypoxic respiratory failure. Despite multiple interventions, his chronic hypercalcemia persisted. Initial investigations ruled out hyperparathyroidism, malignancy, and sarcoidosis. However, further assessments revealed high levels of free retinol, indicating chronic Vitamin A toxicity from his enteral feeding formula.

Key Findings

• Unresolved Hypercalcemia despite conventional treatments, including calcitonin, cinacalcet, and pamidronate.
• Identified Cause: Excessive Vitamin A intake from enteral feeding formula.
• Successful Intervention: Adjusting the enteral feed to a low Vitamin A formula led to normalization of calcium levels within weeks.

Broader Implications for Nephrology Care
According to the American Society of Nephrology, recognizing lesser-known causes of hypercalcemia is crucial for preventing long-term complications in dialysis patients. Proper nutritional assessment is essential, especially in non-verbal and enteral-fed individuals.
