Resistance to Vitamin D or Parathyroid Hormone

Patients with confirmed or suspected states with resistance to vitamin D or parathyroid hormone (PTH) will be admitted for diagnosis and treatment and for inclusion in other protocols. These states include hypocalcemia, rickets, osteomalacia, pseudohypoparathyroidism. Resistance to a factor is manifested by deficient bioeffect despite high levels of the factor ...

Phase N/A

Thiamine Responsive Disorders (TRD) Among Infants in Lao PDR

The study's primary objective is the development of a case definition for TRD among infants and young children with symptoms consistent with TDD, with the case definition being based on those clinical symptoms and other predictors that we find are better able to distinguish those who respond positively to thiamine ...

Phase N/A

Effect of Vitamin D on the Size of Fibroids in Women With Vitamin D Deficiency

Vitamin D supplementation in patients with uterine fibroids who present hypovitaminosis D to re-establish their normal serum values could stabilize the size of the uterine fibroids and thus prevent their growth or reduce their size thanks to the anti-proliferative action of Vitamin D on the myoma cells.
