Vitamin D deficiency: a forgotten treatable cause of motor delay and proximal myopathy

Abstract

We report a four-year-old African boy referred for proximal muscle weakness, fatigability and episodic limb pain. Classical causes of structural and metabolic myopathy were initially considered before clinical and biological features of vitamin D deficiency rickets were identified. Prompt treatment with vitamin D and calcium supplementation led to a complete reversal of the muscle symptoms. Rickets-associated myopathy should be included in the differential diagnosis of proximal myopathy, especially in at-risk individuals. Vitamin D deficiency and its prevention remain important health issues in industrialized countries.
