Previous studies showed that deficiency in vitamin D levels along with disorder in the levels of parathyroid hormone (PTH) was significantly associated with liver fibrosis and components of hepatic dysfunction in patients with CHC [10], whereas the natural history and the treatment of CHC infection were associated with the uptake and the levels of 25-vitamin D in the serum [11]. The gene discussed is PTH; the disease is cryohydrocytosis.
