Hypercalcaemia in infants with Down syndrome is an uncommon condition with only five previous case reports. The patients often present in the toddler years with the classical triad of Down syndrome, biochemical hypercalcaemia, and nephrocalcinosis. We present the sixth case and second male with this condition and further review the clinical details of this under-recognised condition and stratify the diagnostic criteria. The management mandates a reduction in calcium intake as a first step. The natural history of the various aspects of this condition is also considered.
唐氏综合征婴儿的高钙血症是一种罕见病症,此前仅有五例病例报告。这些患者通常在幼儿期出现,伴有唐氏综合征、生化性高钙血症和肾钙质沉着症的典型三联征。我们报告第六例该病症患者及第二例男性患者,并进一步回顾这一未得到充分认识病症的临床细节,对诊断标准进行分层。治疗的第一步是减少钙摄入量。同时还考虑了该病症各方面的自然病程。
