Clinical application of vitamin D metabolites measurement using LC-MS/MS – a case of a patient with persistent hypercalcemia and two pathogenic mutations in CYP24A1 gene and parathyroid adenoma

Leszczynska Dorota , Szatko Alicja , Latocha Julia , Kochman Magdalena , Duchnowska Maria , Wojcicka Anna , Misiorowski Waldemar , Zgliczyński Wojciech , Glinicki Piotr

Introduction: 24-hydroxylase, encoded by a CYP24A1 gene, is a crucial enzyme entailed in catabolism of vitamin D. Loss-of-function mutations of CYP24A1 result in hypercalcemia, not adequately concomitant high levels of 1,25(OH)2D and low PTH levels. The variety of clinical manifestations depends on age – mutations can lead to fatal infantile hypercalcemia among neonates (typically precipitated by supplementation of vitamin D), whereas adults’ symptoms are usually mil...

Polymorphisms in genes related to iron metabolism and DNA methylation and their interaction with estradiol in susceptibility to osteoporosis in postmenopausal women

Aguiar Laura , Ferreira Joana , Paula Barbosa Ana , Rui Mascarenhas Mario , Faustino Paula , Inacio Angela , Bicho Manuel

Introduction: Osteoporosis is a multifactorial disease characterized by reduced bone mass and increased risk of fragility fractures. Menopause predisposes women to osteoporosis due to declining estrogen levels. Iron is known to play a relevant role in the development of osteoporosis since iron suppresses osteoblast formation and may also stimulate osteoclast resorption of bone. Also, homocysteine is a known risk factor for osteoporotic fractures and is related to DNA methylati...

SPECT/CT parathyroid scintigraphy in primary hyperparathyroidism: minimizing the risk of negative results by biochemical parameters assessment

Drynda Anna , Kucharczyk Karolina , Sokolowski Grzegorz , Trofimiuk-Muldner Malgorzata , Hubalewska-Dydejczyk Alicja

Primary hyperparathyroidism (PHP) diagnosis in clinical practice is based on biochemical blood tests. Since a single parathyroid adenoma causes about 85% of cases, the treatment of choice is parathyroidectomy, preceded by imaging studies. Ultrasound and [99mTc]sestamibi scanning can enable adenoma localization. However, the latter method is of higher sensitivity, especially if combined with anatomical imaging. In some cases, the radiotracer uptake in adenoma tissue ...
