Familial systemic lupus erythematosus with hypercalcemia

Area of Science:

• Pediatric Rheumatology
• Endocrinology
• Nephrology

Background:

• Familial systemic lupus erythematosus (SLE) is a rare autoimmune disease.
• Severe manifestations in children necessitate comprehensive understanding and management.
• The interplay between SLE and metabolic bone disease requires further investigation.

Observation:

• An 8-year-old girl with familial SLE presented with severe, life-threatening complications.
• Clinical course included persistent thrombocytopenia, rapidly progressive renal failure, and hepatic failure.
• The patient developed hypercalcemia, hypophosphatemia, and elevated parathormone levels.

Findings:

• This case describes a unique association of hypercalcemia, hypophosphatemia, and elevated parathormone in a child with familial SLE.
• This specific metabolic derangement has not been previously reported in pediatric SLE patients.
• The findings highlight potential endocrine complications in severe pediatric autoimmune diseases.

Implications:

• This case expands the understanding of potential complications in pediatric familial SLE.
• It suggests the need for vigilant monitoring of calcium and phosphate metabolism in affected children.
• Further research is warranted to elucidate the mechanisms linking SLE and parathyroid hormone dysregulation in pediatric populations.
