Primary hypoparathyroidism (HPT) is rarely seen in the clinic, and it can be combined with rhabdomyolysis. There are few reports about this phenomenon. Therefore, it is significant to explore the etiology that is conducive to early diagnosis, timely treatment, and preventing the recurrence.
A 63-year-old man was admitted to our hospital with a severe upper respiratory tract infection and progressing decreased myodynamia of the lower limbs. Blood tests showed creatine kinase > 32000 U/L, creatinine 207.8 µmol/L, calcium 1.28 mmol/L, myoglobin 558.7 ng/mL, and parathyroid hormone 0 pg/mL. He was diagnosed with primary HPT with rhabdomyolysis, and severe upper respiratory tract infection was considered to be the initial trigger. He responded well to supplementation of intravenous calcium gluconate and oral calcium as well as bedside hemodialysis, fluid hydration, infection control, protecting the liver, etc. Creatine kinase, myoglobin, and serum calcium returned to normal, and muscle strength improved significantly. Symptoms improved after symptomatic treatment.
Severe infection should be prevented, which is the key cause of rhabdomyolysis in patients with HPT.
Core tip: We described progressively decreased myodynamia and elevated muscle enzymes in a man with primary hypoparathyroidism. He was eventually diagnosed with rhabdomyolysis and acute kidney injury based on primary hypoparathyroidism. After bedside dialysis, antibiotic treatment, supplementation with blood calcium, and other symptomatic treatments, muscle strength recovered. Regular monitoring of blood calcium and prevention of infection are necessary to prevent recurrence.
