OBJECTIVES: Hypoparathyroidism (HypoPT) is a rare disorder and non-surgical cases require careful evaluation, since may be due to genetic, autoimmune, or metabolic factors.
CASE PRESENTATION: We present a 15-year-old girl with a previous diagnosis of medium-chain acyl-CoA dehydrogenase (MCAD) deficiency due to G985A homozygous mutation. She was admitted to the emergency department with severe hypocalcaemia and inappropriately normal level of intact parathyroid hormone. Main etiologies of primary HypoPT were excluded, so it was suspected to be related to MCAD deficiency.
CONCLUSIONS: The association of fatty acid oxidation disorders and HypoPT has been previously described in the literature, but its link to MCAD deficiency has only been reported once. We present the second case describing the coexistence of both rare diseases. Since HypoPT can be a life-threatening condition, we suggest calcium levels be assessed in these patients on a regular basis. Further research is needed to better understand this complex association.
