Hypoparathyroidism causes severe hypocalcaemia and defective skeletal metabolism. Treatment with calcium and vitamin D supplementation can cause kidney failure whilst native parathyroid hormone (PTH) requires repeated injections and causes renal impairment paralleling high peak and low trough PTH levels. A long-acting PTH, providing constant physiological levels, is needed. LA-PTH, a hybrid of PTH and PTH related peptide, prolongs cAMP responses via altered receptor mechanisms...

Introduction: Leptin is a 16-kDa peptide hormone secreted by adipose tissue and acts as a sensor for energy stores. It feedsback at the hypothalamic arcuate nucleus to suppress appetite. Leptin treatment has been highly effective in suppressing appetite in the rare cases of leptin-deficient obesity and improving the metabolic profile in congenital generalised lipodystrophy. These patients require 2.5–10 mg once daily recombinant leptin treatment. We hypothesised that prol...
